serious personal injury or death.
This indicates a potentially hazardous situation, which if not avoided, could result in
serious personal injury or death.
This indicates a potentially hazardous situation, which if not avoided, may result in
minor or moderate injury. It may also be used to alert against unsafe practices.

1.0System Description
The Nuvair Analyzer Trio measures Oxygen (O2), Carbon Dioxide (CO2), and Carbon Monoxide
(CO) levels in supplied gases. All Analyzers are in a water resistant, impact resistant case with
a clear cover that allows for viewing of all gas displays, visual alarms and easy access to
analyzer controls. This unit is compatible with outdoor and marine environments.
The internal sensors are plumbed together to monitor a single input. Pressurized gases must be
regulated down to atmospheric pressure to avoid damage to the analyzer. The sample flow
rate must be between 1.0 to 5.0 L/min for an accurate reading.
The Analyzer Trio has visual and optional audible alarms for each of the gases monitored. An
audible alarm will sound if any alarm set point is reached.
All analyzers must be calibrated with an appropriate certified calibration gas before operation.
Battery powered units will come equipped with a Lithium battery and dedicated charger. The
Lithium battery charger may also be used as a constant power source. If the user chooses to
use the charger as a power source for an extended period, it is recommended that the Lithium
battery be disconnected from the analyzers to avoid battery damage.
This analyzer is designed for use at atmospheric pressures only. It is not designed for
exposures in a hyperbaric chamber. Use of this analyzer in a hyperbaric chamber will
result in incorrect readings and may damage the unit.
Although the Analyzer is a rugged instrument, careless handling or abuse may result
in damage to the Analyzer components resulting in inaccurate gas analysis. Inaccurate
gas analysis can lead to serious personal injury or death.
Extreme Gas exposure levels directed at the Analyzer sensors may damage the
sensors.

3.0 Requirements for Operation of Analyzer Trio
The Analyzer Trio will require the following connections.
1. Constant gas flow reduced to 1.0 to 5.0 L/min at ATA.
2. Either proper electrical supply to the cord for non-battery units, or 110Volt, 60Hz AC
Outlet to power the lithium battery charger if so equipped.
3.1 Gas Flow
Before using the Analyzer Trio you must connect the analyzer to your
compressor system by diverting regulated gas to the analyzer. This will
require the use of a flow restrictor to reduce the gas to 1.0 – 5.0 L/Min
input. Nuvair sells 3 L/Min flow restrictors for this purpose.See Spares
and Accessories section.
3.2 AC Power
Use the provided AC power supply to plug into 110V power.
For lithium battery powered analyzers, the battery charger may be used as a constant power
supply. It is recommended that should the user choose to do this, the lithium battery should be
disconnected from the system to avoid damage to the cells.
3.3 Gas Sensors
The Analyzer Trio uses three individual analyzers and sensors to measure content in gases of
O2, CO2and CO. The O2, CO2 and CO Sensors are disposable and user-replaceable. The life
expectancy of the O2 sensor is 3 years. The life expectancy of the CO sensor is 4 years. The
life expectancy of the CO2sensor is 5 years. The Sensors are designed for use at atmospheric
pressure. The sample gas mixture to be analyzed must be regulated and any potential pressure
or vacuum must be avoided. Vibration, oil, moisture and particles (contamination) will shorten
the life expectancy of sensors.
